Craftsman 13953985DM garage door opener Parts

Your Craftsman garage door opener model number is printed on the motor unit label; on model 13953985DM, it’s typically on the side opposite the hanging antenna and may be easiest to see after removing the light lens/cover.

Where to look on the opener

Check these common label locations on the motor unit:

• Side panel opposite the antenna wire
• Under or behind the light lens/cover (near the bulbs)
• On the back panel near the wiring terminals
• On the top surface of the motor unit (less common)
• On the same label that lists electrical ratings (voltage/amps)

If you have the paperwork, the model number is also listed in the 13953985DM owner's manual.

What the model label usually looks like

Most Craftsman openers use a printed label with several identifiers. Use the model number for parts lookup.

Label item	What it’s used for	Example format
Model number	Identifies the exact opener version	13953985DM
Part number	Internal assembly reference	Varies
Serial number	Manufacturing identifier	Varies
Electrical rating	Power requirements	120V, etc.

Tips if the label is hard to read

• Turn off power to the opener before removing the light lens/cover.
• Wipe dust off the label with a dry cloth; avoid solvents.
• Use your phone camera and zoom; angled light helps reveal faded print.
• If the label is missing, use the manual and opener features (drive type, remote style, wall control) to narrow it down.

Why it matters

The model number ensures you get compatible parts and correct programming steps for remotes, keyless entry, and safety reversing sensors.

To reset a Craftsman garage door opener model 13953985DM from a previous owner, erase the opener’s memory using the LEARN button on the motor unit, then reprogram your remotes and keypad so only your devices can operate the door. Use the steps in the 13953985DM owner's manual.

Step 1: Erase all previous remotes and keypad codes

1. Locate the LEARN button on the motor unit (on or near the logic board area under the light cover).
2. Press and hold the LEARN button until the learn indicator light turns off (typically about 6 to 10 seconds).
3. Release the button. The opener memory is cleared.

Step 2: Program your remote(s)

After clearing memory, each remote must be added back.

• Press and release the LEARN button; the indicator light stays on for about 30 seconds.
• Within that window, press and hold the button on the remote you want to use.
• Release when the opener lights blink (or you hear clicks).

Step 3: Program a new keypad PIN (keyless entry)

The manual’s programming section uses the LEARN button method:

• Press and release LEARN (indicator light on for about 30 seconds).
• Enter a 4-digit PIN on the keypad.
• Press and hold ENTER until the motor unit lights blink (or you hear clicks).

Quick checks if it still will not work

• Confirm the opener has power and the motor unit lights turn on.
• Replace remote/keypad batteries.
• Stand within range and avoid LED bulbs that can cause radio interference.
• If the door will not close from a remote, check the safety reversing sensors for alignment and obstructions.

Why it matters

Resetting the memory removes unknown remotes and keypad PINs from the previous owner, which restores control of access to your garage and prevents unexpected operation.

Task	What it does	When to do it
Erase memory (hold LEARN)	Deletes all remotes and keypad codes	First step after moving in
Program remote	Adds your handheld remote	After memory erase or new remote
Set keypad PIN	Adds your chosen 4-digit PIN	After memory erase or new keypad

The three most common garage door opener drive types are chain drive, belt drive, and screw drive. For your Craftsman garage door opener model 13953985DM, the best choice depends on your priorities (noise level, maintenance, and cost); our 13953985DM owner's manual helps you confirm what your opener uses and how to maintain it.

Quick comparison of the 3 drive types

• Chain drive: Uses a metal chain to move the trolley; durable and typically the most budget-friendly.
• Belt drive: Uses a reinforced belt; usually the quietest option and a great fit for attached garages.
• Screw drive: Uses a threaded steel rod; fewer moving parts, but can be louder and may need periodic lubrication depending on conditions.

Drive type	Noise level	Typical upkeep	Best for
Chain	Medium to loud	Check chain tension, lubricate door hardware	Value, heavy doors
Belt	Low	Inspect belt condition, keep door balanced	Quiet operation
Screw	Medium	Lubricate screw (as applicable), inspect travel	Simpler mechanism

How to identify what you have on a Craftsman opener

• Look at the rail: a metal chain is obvious; a rubber/composite belt looks like a toothed strap.
• Listen during travel: chain drives often have more vibration and rattle.
• Check the opener head and rail labeling and diagrams in the 13953985DM owner's manual.

Why it matters

Drive type affects noise, maintenance, and how smoothly the opener runs. No matter the drive, the door itself must move freely. If the garage door binds, sticks, or is out of balance, we treat that as a door issue first; the manual advises having a trained door systems technician correct door balance and hardware problems before adjustments or installation.

Helpful related troubleshooting

If you are choosing a drive type because the opener is acting up, start with error and diagnostic info:

Yes. A universal remote typically works with the Craftsman 13953985DM garage door opener as long as it supports the same programming method and security type (rolling code). You will program it using the opener’s LEARN button, just like adding an additional Craftsman remote.

How to confirm compatibility before you buy

Most “universal” remotes cover multiple Craftsman/LiftMaster/Chamberlain systems, but you still need a match on the opener’s radio/security format.

• Check the universal remote’s compatibility list for Craftsman 13953985DM
• Confirm it supports rolling code (often labeled Security+ or similar)
• Verify it can learn using a LEARN button method (not DIP switches only)
• Plan to program it from the motor unit (ladder access is usually required)
• If you have multiple doors, confirm it supports multiple channels/buttons

For model-specific programming steps, use the 13953985DM owner's manual.

How to program a universal remote (LEARN button method)

Programming is usually a 30-second window:

1. Press and release the LEARN button on the motor unit (the indicator light stays on briefly).
2. Within that window, press and hold the button on the universal remote you want to use.
3. Release when the opener lights blink or you hear clicks; the remote is learned.

If you are adding several remotes, program them one at a time so you can confirm each one works.

If the universal remote will not pair

These are the most common fixes we use in the field:

• Replace the remote battery and retry programming
• Move closer to the opener during programming
• Clear the opener’s memory, then reprogram all remotes (use this if you suspect a “stuck” code)
• Check for LED bulbs in the opener that can cause radio interference; swap to garage-door-opener-rated bulbs
• Inspect the safety sensor alignment if the door moves inconsistently after pairing

Quick comparison: universal vs OEM-style remote

Option	Best for	Tradeoffs
Universal remote	One remote for multiple brands/doors	Must match security format; setup varies by remote
Craftsman-compatible remote	Simplest pairing on Craftsman systems	May control fewer device types

Why it matters

Using the correct rolling-code compatible remote keeps your Craftsman 13953985DM operating reliably and avoids pairing failures that look like a bad receiver, wall control, or logic board.

A Craftsman garage door opener typically lasts 10 to 15 years. For the Craftsman 13953985DM, lifespan depends most on daily cycles, a properly balanced door, and routine care steps outlined in the 13953985DM owner's manual.

Typical lifespan and what wears out first

Most openers fail from normal wear in a few high-use areas:

• Drive system wear (chain/belt, sprockets, trolley components)
• Logic board or wall control issues (intermittent operation, no response)
• Safety sensor problems (misalignment, wiring damage, sunlight interference)
• Motor strain caused by a heavy or unbalanced garage door
• Limit/force settings drifting after door hardware changes

Maintenance that extends life

Use these habits to keep the 13953985DM running longer and reduce strain on the motor:

• Test door balance; the door should stay mid-travel when disconnected from the opener
• Keep safety sensors aligned and lenses clean
• Check mounting hardware and rail support for looseness and vibration
• Re-test safety reversal and sensor operation after any adjustment
• Follow the “care of your garage door opener” and adjustment procedures in the 13953985DM owner's manual

Quick guide: repair vs. replace

What you’re seeing	Most likely direction	Why
Door reverses or won’t close, lights blink	Repair/adjust first	Often sensors, force, or travel limits
Motor runs but door barely moves	Repair first	Door balance, drive wear, or gear issues
Random operation, wall control acts up	Repair first	Control wiring or logic board symptoms
Multiple major issues and heavy daily use	Replace	Cost and downtime usually outweigh repairs

Why it matters

A garage door opener’s “life expectancy” is really a measure of how hard the opener has to work. A smooth, balanced door and correct force and travel settings reduce motor load, protect internal gears, and keep the safety reversal system working as designed.

Common problems on the Craftsman 13953985DM garage door opener include safety sensor alignment or obstruction (door will not close and lights blink), remote or wall control issues (lock mode on, lost programming), and drive or motor wear that causes grinding noises or a door that reverses unexpectedly. See the 13953985DM owner's manual for model-specific checks.

Most common symptoms and what they usually mean

• Door will not close; opener lights blink: Safety reversing sensors are misaligned, blocked, or not connected.
• Remote will not run the door: Lock mode may be enabled on the wall control, the remote may need reprogramming, or there may be interference.
• Door starts down then reverses: Safety sensors are interrupted, travel/force settings are off, or the door is binding.
• Grinding or clicking from the motor unit: Worn drive gear/worm gear or a failing drive system (common on chain-drive units).
• No response at all: Power issue (outlet, breaker, wiring) or a failed logic board.

Quick checks we recommend (safe DIY)

1. Check the safety sensors: Make sure both sensor indicator lights are on, the lenses are clean, and nothing blocks the beam.
2. Test the safety reverse: With the door closing, interrupt the sensor beam; the door should stop and reverse.
3. Look for diagnostic flashes: Count the motor unit diagnostic LED flashes and match them to the chart.
4. Confirm wall control settings: If the wall control is blinking, turn off Lock Mode.
5. Reprogram remotes/keypad: Relearn the remote to the opener if it stopped working after a power outage.

Troubleshooting guide by symptom

Symptom	Most likely cause	Best next step
Lights blink; won’t close	Sensor misalignment/obstruction	Align sensors; clear beam; verify wiring
Remote won’t work	Lock mode, dead battery, lost programming	Disable lock mode; replace battery; reprogram
Reverses unexpectedly	Sensor interruption, force/travel out of adjustment	Clear beam; verify door moves freely; adjust per manual
Grinding noise	Worn gears/drive components	Inspect drive; plan gear or motor service

Why it matters

The safety reversing sensors are designed to prevent injury and property damage. If the opener closes when the sensor beam is blocked (with sensors installed low near the floor), we recommend having a trained door systems technician correct the installation and safety setup.

For code-based troubleshooting, use Craftsman error codes.

To reprogram the keypad on your Craftsman garage door opener model 13953985DM, press the opener’s LEARN button, then enter a new 4-digit PIN on the keypad and hold ENTER until the opener lights blink (or you hear two clicks). Use the steps in the 13953985DM owner's manual for the exact button locations.

Reprogram a new PIN (keyless entry)

1. On the motor unit, press and release the LEARN button; the learn indicator stays on for about 30 seconds.
2. Within 30 seconds, on the keypad enter a new 4-digit PIN.
3. Press and hold ENTER.
4. Release ENTER when the opener lights blink (or you hear two clicks). The keypad is programmed.

Change an existing PIN (when you know the current PIN)

If you already know the current PIN, you can change it without using the LEARN button:

• Enter the current 4-digit PIN.
• Press and hold # until the opener light blinks twice.
• Enter the new 4-digit PIN, then press ENTER.

Quick checks if it won’t program

• Make sure you press ENTER before the 30-second learn window ends.
• Stand close enough to the door so you can see the opener lights confirm programming.
• Replace the keypad battery if the keypad is dim or inconsistent.
• If you recently moved in, erase old devices first, then reprogram everything.

Erase all codes first (optional, but helpful after a move)

What you want to do	What to press	What you should see
Erase all remotes and keypad codes	Press and hold LEARN (about 6 seconds)	Learn indicator turns off
Add keypad PIN again	LEARN, then PIN + hold ENTER	Lights blink or two clicks

Why it matters

A properly programmed PIN helps your 13953985DM open reliably from outside the garage and prevents old remotes or unknown keypads from operating the door.

Related help: If your opener is flashing diagnostic lights or acting erratically, use Craftsman error codes to match the blink pattern to the fix.
